In 2016 TROPICAL has launched a Soft Line – a unique line of Super Premium foods for fish. These innovative soft-textured foods are highly nutritious, easily assimilable and do not disintegrate in water. Soft, non-swelling granules equal easier digestion and greater safety of the fish. Their high hydrostability limits leaching of nutrients into the water to keep its good quality. Soft Line granules contain carefully selected raw materials such as herring, crustaceans, insect larvae and a few species of algae.
